Git is a distributed version control system that allows users to work with complete repositories locally and then sync them with a server.
Version control systems track and manage changes to software code, helping software teams manage code changes over time.
GitHub is a popular version control platform known for its extensive marketplace of third-party integrations, while GitLab remains open source with a smaller integration selection.
GitHub's popularity increased after being acquired by Microsoft in 2018, leading to promotions and improved features.
A .yml file, or YAML file, is a human-readable data serialization format commonly used for configuration files and data exchange.
YAML stands for "YAML Ain't Markup Language" and is used for writing configuration files.
Other version control systems include Subversion (SVN), Mercurial, and Perforce.
